J OINT-PLATE.

Specification of Letters Patent.

Patented Apr. id, 1914.

Application filed November 6, 1913. Serial No. 799,428.

To all whom it may concern:

Be it known that I, ALBERT MoYEn, a citizen of the United States of America, residing in the city, county, and State of New York, have invented certain new and useful Improvements in J oint-Plates, of which the following is a true and exact description; reference bein had to the accompanying ldrawings, whic form a part thereof.

y invention relates to joint plates for roads made of concrete or like material and has for its object to provide a joint plate which without excessive use of metal will, at the same time, provide proper protection for the edge of the road section and have the capacity of self support at the proper surface level of the road.

A further object which I have in view is the provision of a simple composite expansion and protective joint made up of joint plates having a novel construction which forms the essential part of my invention used in pairs and clamped upon tar paper or like compressible material adapted to permit of the necessary expansion of the road sections.

My invention will be best understood as described in connection with the drawings, in

Figure 1' is a perspective view showing my improved joint plates clamped upon expansible material, and Fig. 2 is a cross-sectional view on the line 22 of Fig. 1.

The plate A is generally and best constructed of mild steel and is slit, as shown, to form tongues B B and C C, etc. The tongues'B B, etc., being bent out at right angles to the plate and preferably provided with slit bent ends, as shown, to enter and anchor the plate in the edge of the concrete section for which it forms a joint plate. The tongues C C are bent downward; as

shown, and are formed of such length that their ends G will rest upon or preferably penetrate to a short distance the sub-base of the road so that when supported upon these depending ily be ad usted and held at the proper surface level of the road.

The best mode of use of these plates in forming the usual expansion joints for concrete roads is to place between a pair of the plates compressible material, preferably several sheets of tarred paper, as indicated at D, and clamp the plates together upon this material, by some convenient mecha- 'nism which will at least temporarily and until the roadway is finished hold the parts together; wire ties, as indicated at E, are

eflicient and satisfactory clamping devices and a clip, as indicated at F, can conveniently be used at the upper edge of the plates.

Having now described my invention, what. I claim as new and desire to secure by Letters Patent, is:

1. A joint plate for concrete roads consisting of a plate of less depth than the concrete haying laterally projecting tongues adapted to be embedded in the concrete and having downwardly projecting integral legs adapted to rest on or in the sub-base of the road.

2. A joint plate for concrete roads consisting of a plate of less depth than the concrete said plate being slit to form two sets of integral tongues one set being bent outward to extend into the concrete and the other set being bent downward to form supporting legs for the plate.
